1. If the Siniperca chuatsi species with a body length of about 3cm are stocked, it is more appropriate to stock about 2,000 per mu; Stocking about 0/000-8000 fish per mu, and 6- 10cm in length is more suitable. There are also cases of stocking about 3000 tails per mu.
2. If the annual mandarin fish species (weighing about 50- 100g/ fish) are cultured, there are usually about 500 fish per mu, and 200 flowers, silver carp and 200 old crucian carp are cultured together.
3. In addition, the reasonable stocking density should be determined by comprehensive consideration of pond conditions, water quality, bait source, breeding technology and other factors. Before stocking, fry should be soaked in a certain concentration of salt water or potassium permanganate solution and disinfected to improve the survival rate of fry.
